She Lied
Ivanka had lied to the Red Cross about her story! Her parents weren’t Ukrainian: they were Russian! They did actually live in Donbas, and they had been killed in the war. But they were a part of the Russian population. They had probably died in one of the attacks from the Ukrainian army.
But why did Ivanka lie about that? Why did she conceal her story? When she was questioned about it, the truth came out.
